The vendor has provided us with a BT that has over 5000 trades. Remember that this type of strategy is a "hold-and-hope" style basket trader. The fact that it survived this BT is saying some good things indeed.
You will note 5538 trades in just over 3 years trades. Over 6% monthly gain with a max. DD of around 46.6%.
According to the vendor this EA uses the Stochastic indicator (and some others) for its entries on the H1 timeframe. This apparently filters out false signals and makes this a safer trading sytem when compared to other martingale systems.
The vendor has a forward test running that is worthy of note:
This account has not had a losing month since its inception in Sept. 2012. It is running at a 30% monthly clip with around 34% max DD. This is not surprising to me as the markets have not been trending strongly for quite some time now.
While I cannot recommend any type of strategy like this, if you have a higher risk appetite and a ton of leverage to play around with, this might appeal to you. Please let me know if you are going to run this and share your experience with us.
